Description

[Detailed description of the invention] A tire transport jig used for transporting unvulcanized or completed BakaV tire carcass between υ and storing the carcass between these operations. Regarding.

BACKGROUND OF THE INVENTION In general, a newly completed tire or a tire carcass is transported by hanging it from a hook or saddle, or by placing it on a hammock. The hammock is constructed from a flexible strip of material wider than the tire and is adapted to retain the tire around the lower outer edge of the hammock. However, either of these transportation methods deforms the uncured tire, and if the tire is left uncured for an extended period of time, the quality of the tire deteriorates.

The purpose of the present invention is to provide a tire that is ready to use! To provide a transportation jig that can be transported without being deformed.

According to the invention, the tire transport jig comprises a horizontally fixedly arranged lower bead support, a horizontally fixed and concentrically arranged tire shoulder support, and an upper bead retaining device. a set of upper bead retaining members in which the upper bead retainer is movable in a radial direction, a first position in which the upper tire bead is engaged and a second position in which the retainer is disengaged and means for effecting said radial movement between.

The lower bead support and the tire shoulder support are preferably engaged with each other by an annular member.

The layer support can also be a conical surface arranged to contact the tire shoulder when the tire is installed with the lower bead of the tire resting on the lower bead support.

Means for effecting radial movement of the retaining member of the upper bead comprises a single control member and a plurality of engagement members from the control member such that movement of the control member moves the retaining member in a synchronous manner. Equipped with a connector to contact. The connector is
Preferably, a strut is provided pivotally connected between each engagement member and the control member. Each engagement member may comprise a lever pivotally mounted at its lower end and movable radially inwardly and outwardly by a strut connected to its upper end. The control member may also be a piston that slides within a guide extending along the axis of the annular member. The piston is preferably biased upwardly by a spring to push the retaining member radially outward when the piston is in the released position and to push the retaining member radially outwardly when the piston is moved against the biasing force of the spring. The mating member can be moved radially inward. Preferably, the spring force forces the piston upwardly along its axis. In addition, a contact surface is provided at the upper end of the piston,
By depressing the piston and moving the retaining member inwardly, the tire loading device opens the jig and allows the tire to be loaded. Alternatively, the spring force can be applied in the opposite direction to actuate the piston from the underside of the jig.

The engagement members of the upper bead preferably consist of fingers thrown at equal intervals around the circumference 9 of the tire bead. Thus, a set of spaced apart carrier fingers on a jig loading device may be used to load tires onto a jig. An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

EXAMPLE The tire transport jig comprises a steel disc base plate 1 mounted horizontally on a tubular central column 2. The support for the lower tire bead is an annular support ring 3
It is made up of. This annular support ring 3 obviously has a diameter that matches the tire to be transported and a thickness that, depending on the position of the tire in the jig, reaches the bead of this tire. An annular tire shoulder support ring 4 is arranged in the outer circle 5 of the base plate 1. The support ring also includes a conical tire shoulder engaging surface 6. This surface 6 is arranged upwards with respect to the support ring 3 of the lower bead and is adapted to rest against the tire to be transported. The bead support ring 3 and the shoulder support ring 4 can be constructed separately as shown in the drawing, or they can be constructed integrally.

There are four upper bead retaining fingers 7 spaced around the jig. Each finger 7 comprises a strut with a lower end 8 pivotally mounted to the base plate 1, the upper end 9 of which can be moved radially inwardly and outwardly.

The upper end 9 has a grooved or knurled outer surface where it contacts the upper tire bead.

Each bead retaining finger 7 is connected to a vertically sliding portion 11 within the central column 2 via a working post 10i. The piston 11 is pressed upward against the limit stop layer 12 by a coil spring 13 . The struts are also geometrically arranged so that when the piston 11 is in the uppermost position, all the fingers 7 are in the radially outer position. Therefore, when the piston 11 moves downward relative to the coil spring 13, all four fingers move radially inward.

To load tires into a transport jig, the jig is placed as shown in FIG.
Press down (see Figure 2). This action causes the fingers 7 to pivot inwardly, e.g. for a tie held by four carrier fingers 15. It can be dropped into a begging jig. The shoulder of the tire contacts the conical surface 6 and the lower bead contacts the lower support 3. Although both jig fingers 7 and carrier fingers 15 are shown in FIG. 2, in reality these fingers would be spaced around the tire, with one set of fingers 15
carrier fingers) are circumferentially spaced apart from the fingers 7 of the other set. When the release pin 14 is then lifted from the jig, the spring 13 moves the piston 11 to bring the four fingers 7 into contact with and hold the upper tire bead. Finally, the carrier fingers 15 can be removed from the tire and fully installed as shown in FIG. 3 on a jig for transporting the tire to some other location.

Although not shown, as a modification, the piston 11 may be pressed downward instead of upward. The piston is pushed downward to move the fingers 7 radially inward, and the 1% removal bottle 14 may be replaced by an actuating post installed separately from the jig on the underside of the base plate. Pillar 10,
By changing the geometry of the fingers 7 and one piston 12, when the entire jig is lowered onto the working post, the pistons are pushed upward against the force of the spring, forcing the fingers 7 radially inward. You can also move the tire to a jig. When the jig and tire are lifted from the working post, the piston moves downwardly and the fingers 7 move radially outward relative to the upper bead of the tire to securely hold the upper bead of the tire to the jig. .

ADVANTAGES OF THE INVENTION In this way, the jig is able to hold the tire in such a way that it maintains the shape of the fresh tire and can be loaded and unloaded by mechanical means. According to the present invention, the above object can be achieved with the above configuration.
